So this is a weird one. My iPhone has suddenly stopped allowing voice calls and voice notes, incoming and outgoing.
I’ve done a full reinstall as new, and it’s still there.
This is what happens: when I receive an incoming voice call, neither party can hear anything, but the line connects. If I try to make an outgoing call, it just snaps back to the keypad.
If I receive a WhatsApp voice/video call, I try to answer and it says call failed. If I receive a voice note, it won’t play. And it won’t let me send a voice note.
The phone is connected fine to wifi and 4G. The speaker works fine (when playing videos/notifications). It’s just with calls. Everything else on the phone seems to be working fine.
Any ideas what this might be?
